The R-44 WESTCODE brake package does not use a feed valve andtherefore the brake pipe will charge up to the compressor governor cut-out pressure. If there are no significant leaks in the brake pipe, that pressure will remain sealed in, but if there is a leak, there is no "excess pressure" in the main reservoirs above brake pipe pressure, so it will fall. This isn't really a problem since it is the rate of brake pipe fall which causes a BIE, not the absolute pressure. As long as the BP stays above about 70#, the emergency contactors will stay in. |
